Phillip K. Dick is a philosopher in a pulp writer's body. His books reads like pulp fiction in style but are loaded with philosophical inquires regarding reality and perception. Sometimes so much so that the text can't keep up with it. Flow My Tears, The Policeman Said is one example. The plot centers around a celebrity who finds himself no longer remembered. To be more precise, he no longer exists. All his identity is wiped out and no one knows him not even his friends. This is actually one of his more straight forward stories but all the gimmicks of a Dick novel are there; the mind altering drugs, people removed from a safe environment into the unknown, police states and malevolent authorities. Some of this may seem well worn to the casual reader However it is important to realize no one was writing stories like this before Phillip K Dick. Flow My Tears is a good read but I would recommend a couple others before this one, like Man in The High Castle, Do Androids Dream of Electric Sheep or Martian Timeslip. But whatever you choose, anyone into science fiction or even 20th century literature, should read at least one Dick novel.
